WHAT IS DOUBLE GLAZING WINDOW

A double-glazing window has two sheets of glass set into a frame to create two layers of glass with an intervening gas or air pocket to better insulate a room. This window is sometimes referred to as a double-glazed window. An insulating glass unit (IGU) is a type of double-paned (or multi-paned) window.
